SHOOTING BOARD AND PLANE.

SPECIFICATION forming part of Letters Patent No. 463,924, dated November24, 1891.

Application filed May 26, 1891. Serial No. 394,234. (No model.)

To all whom it may concern.-

. Be itknown that we, CARL SCHRAUBSTADT- ER, J r., and CHARLES R.SOHILLING, of St. Louis, Missouri, have invented a certain new anduseful Improvement in Shooting Boards and Planes, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

Our invention relates to certain improvements in shooting; boards andplanes which are intended more particularly for use in trimmingstereotype-casts and like articles.

Our invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is a perspective view of our improved machine. Fig. II is anenlarged per spective view of the plane. transverse vertical sectionthrough the board and plane, taken on line III III, Fig. I. Fig. IV is asimilar View taken on line IV IV, Fig. I. Fig. V is a detailedhorizontal section illustrating the manner of holding the cut ting-bladeof the plane in place. Fig. VI is an enlarged detail elevation showingthe manner of adjusting the cutting-blade of the plane edgewise.

Referring to the drawings, 1 represents the shooting-board, which may besupported on suitable legs 2. The board has a race 3, in which the plane4 fits and moves. The plane is operated through means of a pitman 5,connecting it eccentrically to a band-pulley 6. The plane has anextended side 7, formed with a T-groove 8 to receive the head of thebolt 9, by which the inner end of the pitman is made fast to the plane,so that by loosening on the nut of the bolt the pitman may be adjustedrelatively to the plane, and thenafter tightening the nut again thepitman will be held to its adjustment, and thus the throw or movement ofthe plane can be regulated or adjusted.

10 represents the cutting-blade of the plane, which rests with its loweredge upon a protuberance 12, (see Fig. VI,) upon which it is held byvertical set-screws 15, one on each side of a Vertical line through theprotuberance. By adjusting the set-screws 13 it will be observed thatthe vertical position of the Fig. III is a blade may be changed at will,and when both screws are tightened the blade will be permanently heldfrom movement on the protuberance. The blade is held from horizontalmovement by means of a lever 14, pivoted at 15 to the body of the plane,so that its inner end 16 will bear against the inner end of the blade10, (see Fig. V,) and its outer end is provided with a set-screw 17,adapted to jam against the outer end of the blade, so that by tighteningon the set-screw the blade will be permanently held from horizontalmovement. By means of this lever and setscrew and by means of theprotuberance 12 and set-screws 13 the blade can be readily adjusted ineither direction, and when ad- 3' usted securely held from movement ineither direction.

The portion 18 of the plane fits in an opening 19 of the race 3 of theshooting-board, with its shoulders or flanges 20 resting on the uppersurface of the race. Secured to the part 18 of the plane beneath therace is a strip 21, held to the plane by means of setscrews 22. (SeeFig. III.) By tightening on the screws 22 any wear between the plane andthe race may be taken up, and thus a snug fit of the parts alwaysmaintained. For the purpose of taking up any wear between the verticalsides of the part 18 of the plane and the vertical walls of the opening19 of the race, in which the part-18 fits, we locate a. gib piece orstrip 23 between one side of the part 18 of the plane and the wall ofthe opening 19, and to adjust this gib piece or strip to compensate forthe wear we place threaded plugs 24: in openings or sockets 25 in thepart 18 of the plane, these plugs having small necks 26, fittingin'holes inthe gib-piece 23. The ends of the necks 26 have grooves, asshown in Fig. II, so that by applying a screw-driver the plugs may beadjusted in their sockets, so as to move the gib-piece outwardly andtake up any wear between the sides of the part 18 and the walls of theopening 19 in the race. The side 27 of the shooting-board has openingsor perforations 28, through which the screw-driver maybe passed when theplane is adjusted to bring the plugs in line with the openings 28.

The side 27 of the shooting -board is strengthened bydownwardly-extending lugs 20, connected to the body of the shootingboard by bolts 30, surrounded by sleeves 31, and the front end of theside 27 has a bridge 32, which straddles the pitinan 5 and forms aconnection between the forward end of the side 27 and the other side ofthe shootingboard.

The operation of the machine, which will explain its function, is asfollows: The stereotype-cast or other object to be trimmed is placed onthe table or board 1, with the edge to be trimmed presented to theplane. The plane is then reciprocated through means of the pulley G andpitman 5, and at each forward stroke it takes a shaving off the east, asin the use of an ordinary hand-plane. \Vhen one edge is trimmedsufficiently, another edge of the cast is presented to the plane.

"0 claim as our invention- 1. In a shooting board and plane, thecombination of the blade 10, a protuberance on which the lower edge ofthe blade rests, setscrews 13 for holding the blade on the protuberance,a pivoted lever 1i, having an end 16 bearing against the cutting end ofthe blade, and a set-screw 17, passing through the outer end of thelever andbearing against the outer end of the blade, substantially asand for the purpose set forth.

2. In a shooting board and plane, the com bination of the plane 4,having a shoulder 20 and a portion 18 fitting in the slotted race of theshooting-board, a plate 21, secured to the part 18 of the plane byset-screws 22, a gib-piece :33, located at one side of the part 18 ot'the plane, and adjusting-plugs fitting 1n sockets and having necksfitting in holes in the gib-piece, substantially as and for the purposeset forth.

The combination of the plane l, fitting in the slotted race of theshooting-board, and a pitman connecting the plane to a drivingpulley,said shooting-board having a side 27, provided with lug or lugs 29,secured to the body of the board by bolts and sleeves 31, and a bridgeconnecting the front end of the side 27 with the other side of theshooting-board, substantially as and for the purpose set forth.
